APPARATUS AND METHOD FOR CONVERTING AN INFORMATION SIGNAL TO A SPECTRAL REPRESENTATION WITH VARIABLE RESOLUTION - The apparatus for converting an information signal from a time to a variable spectral representation includes a means for windowing the information signal, a means for converting the windowed information signal to a spectral representation, and a means for weighting a set of information signal spectral coefficients with several sets of complex base function coefficients provided from a means for providing the sets of base function coefficients. The sets of base function coefficients are derived from base functions of various frequencies by windowing and transform, wherein several sets of base function coefficients are provided for one and the same base function for base functions of higher frequencies, wherein the windows for providing these sets are related to various time portions of the base function. The variable spectral representation exhibits variable bandwidth of the variable spectral coefficients, which are efficient and accurate to calculate and especially suited for music analysis purposes.

Surgical Instrument - A surgical instrument has a shaft, an end effector comprising at least one movably mounted tool element and defining a longitudinal axis, and a force transmitting member mounted in the shaft for movement in the distal and proximal directions for transmitting an actuating force introduced at a proximal end of the instrument onto the end effector in order to move the at least one tool element from a first tool element position to a second tool element position and/or vice versa. The at least one tool element is pivotably mounted on a bearing shaft held on the shaft. The at least one tool element is connected by at least one articulation member, at least a section of which is flexible, to the force transmitting member in order to transmit the actuating force from the force transmitting member onto the at least one tool element.

METHOD FOR PRODUCING A PROTON-CONDUCTING, STRUCTURED ELECTROLYTE MEMBRANE - In a method for producing a proton-conductive, structured electrolyte membrane, particularly for a fuel cell, a coating, which comprises at least one ion-conductive cross-linking component having at least one acid group and at least one photoactive substances interacting therewith, is applied onto a solid body surface. The coating is optically masked in that at least one region of the coating, in which the electrolyte membrane is supposed to be, is exposed such that the cross-linking component cross-links with the photoactive substances to form a polymer and/or copolymer network adhering to the solid body surface. At least one unexposed region of the coating is removed in order to structure the electrolyte membrane.

Method for Producing Finely Structured Surfaces - A method for producing finely structured surfaces, in particular in plastics, includes a) applying at least one coating compound on at least one substrate; b) forming a fine structure by a die, which has the negative of a fine structure, c) curing the resultant finely structured coating compound, obtaining a substantially cured coating; and d) separating the finely structured coating from the die, wherein steps d) and c) can also be carried out in the reverse order.

Electrical Voltage Supply - A voltage supply has a plurality of voltage sources to supply output connections. To achieve closed-loop control of the output voltage at the output connections, a closed-loop control circuit is provided that has an actuating element for each voltage source, and each respective actuating element has a current path via which a connection of the respective voltage source can be connected to an output connection. Each actuating element has an actuating signal input for setting the electrical conductivity of its current path. The closed-loop control circuit has a closed-loop controller to which the output voltage and a desired voltage signal are supplied. When a deviation occurs between the output voltage and the desired voltage signal, the closed-loop controller interacts with at least one actuating signal input in order to reduce the deviation. The actuating signal inputs are connected to a control device that is designed in such a way, that the current path of at least one actuating element is enabled for control by the closed-loop controller if the output current that is drawn at the output connections is present in a predetermined value range assigned to the respective actuating element, and the current path is disabled if the output current that is drawn at the output connections does not lie in the predetermined value range.
